All cranial sutures

All cranial sutures

coronal suture

•separates the two parietal bones from the frontal lobe of the skull

lambdoid suture

•separates the temporal bones of the skull from the occipital bone.

sagittal suture

•separates the left and right parietal bones of the skull in the midline.

squamous suture

• separate the parietal bones from the superior portion of the temporal bones.

occipitomastoid suture

•separates the occipital bone from the mastoid portion of the temporal bone.
